Becka interrupts me

The door to your office creaks open without warning. Your head snaps up from the spreadsheet, coffee sloshing slightly in your cup as Becka saunters into the room. She's wearing the same baby blue boycut panties, they're paired with a thin white tank top that clings to her curves. Her breasts shift visibly beneath the fabric as she moves, her nipples dark against the stretched cotton.

"Morning, big brother," she says, flopping onto the leather couch in the corner of your office. The motion makes her shirt ride up, revealing a sliver of smooth skin above her panties.

Becka stretches out on the couch, her legs crossing in a way that makes her panties ride up even further. She props her head up on one arm, looking at you with a playful smirk. "I saw your pretty little wife leave a little bit ago. She said something about an early meeting tomorrow out of town. Guess that means you're all mine for the night."

She bites her lip, her free hand idly tracing patterns on her thigh. "So... what are we gonna do, big brother? Wanna watch a movie? Play some games?" Her fingers creep higher up her leg, the fabric of her panties straining against her hips. "Or maybe just talk... about what happened last night?"

You lean back in your chair, watching as she plays with herself right in front of you. Her fingers tease at the edge of her panties now, dipping just below the fabric to toy with the elastic waistband. She catches your gaze and smiles knowingly.

"C'mon Dan," she purrs, "you know you want to ask." She arches slightly, pushing her chest out just enough to make the thin fabric of her shirt strain against her nipples. They're hard now, standing up visibly through the material.

"What exactly did you see last night?" you finally ask, your voice rough with need. Becka grins, rolling onto her side to face you fully. Her fingers stop their teasing motion, and she lets out a soft, breathy laugh. "Oh, I saw everything, Dan. The way Megan was sucking your cock... the way you were watching me in the dark." She slides one hand beneath the waistband of her panties, her eyes locked on yours. "I saw you looking at me while she rode you. I saw how hard you got when you realized I was touching myself, imagining it was me bouncing on your big cock instead of her."

She shifts on the couch, parting her legs slightly. You can see the damp spot forming on the light blue fabric between her thighs. "I came so hard, Dan."
